SPECIFICATION forming part of Letters Patent No. 293,023, dated February 5, 1584` Application filed Xovembcr l5, 1853. (No model.) Patented in Germary November :24, 1532, Noh.

Be it known that I, ARTHUR B. HIL- '.rAWsKI, of Zaborze, Upper Silesia, Germany, have invented a new and Improved Goking- Furnace, of which-the following is a full, clear, and exact description.

The object of my invention is to provide a new and improved furnace for converting coal into coke, in which furnace all the Vgases eX- y chambers, so that the gases will circulate until exhausted, and then pass off through a suitable channel leading to the smoke-stack.

Reference is to be had to the accompanying drawings, forming a partv of this specication, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a cross-sectional: elevation of my improved coking-furnace on the line :c Fig. 2. Fig. 2 is a sectional `plan view of the same on the line y y, Fig. 1. Fig. 3 is a lonu gitndinal sectional elevation of the same on the line a" a', Fig. l. Fig. 4 is a longitudinal sectional elevation of the same on the line y y', Fig.` 1. f

rlhe furnace A is constructed with a series of longitudinal chambers, B, which have curved roofs, and are provided with one or more openings, G, in the said roofs, through which open-` ings the coal to be converted into coke is passed into the chambers. Between each two chambers B gas-chambers D are formed, into whichthe gases from the coking-chambers pass, the walls of the cokingchambers being provided with slots E, inclined upward at an angle of aboutfourteen degrees to the `bottoms of the chambers B, through which slots the gases pass from the coking-chambrs into the gas-chambers. The walls of the gas chambers D are united at intervals by bricks D', extended across the gas-chambers. The gas-chambers areV provided in their bottoms with openings F, through which the gases pass into transverse channels G, which conduct them into longitudinal channels H below the coking chambers B. The bottoms of the coking-chambers are the roofs of the channels H, and the said bottoms are provided with a series of longitudinal slots, J. Each channel H is providedY with a downwardly-extending flue, H', 'which leads to a transverse channel, K, connected with a smoke-stack,| L. The openings F in the floors of the gas-chambers D can be closed by means of sliding blocks F, resting on the floors of the gas-chambers,

which gate-blocks can be moved by means of hooks or rods introduced through openings M in the end walls of the chambers. Each channel H -under the chambcrsB is provided at its ends with openings N, through which hooks can be introduced to remove the slags, o., from the slots or openings J. Like openings O are provided for introducing hooks to clean the slots F. The openings N and O,` can be closed by means of cla-y blocks l). The air enters throughopenings R iu the front and rear walls of the gas-chambers D', which openings can be closed more or less by means of suitable slides. The gases from the coal pass through the slotsE into the gas-chambersD, lfrom there through the openings F into the channels G and H, and from these channels up through the openings J, through the coal again, and so on, and only the worth- Y less gases-that is,the non-combustible gasespass off through` the channel K and thesmokestack L. All the heat in the gases is utilized and none islost. The chambers archeated to such an extent that if the coke is removed and fresh coals are placed into the chambers the gases will be driven out immediately, and the process of coking4 begins as soon as the .coals are placed in the furnace. The coke Patent- IOO A coking-furnace constructed with a series and the eoking-ehamber B, substantially as of coking-hambers, B, gas-chambers D beherein shown and described, and for the pur- 1o tween them, longitudinal channels H`beloW pose set forth. the @king-chambers, transverse channels G, y 5 connecting the Channels H, and a channel, K, ARTHUR RICHARD BALDWD HHTA SM communicating with the channels I-I by the Witnesses:

ues H', and leading to the smoke-stack, and JOSEF KAHNERT, v slots J, communicating with the channels H l RICHARD PAUL LUDWIG FELKEL.
